Update 12/25/2008: Refreshes are out...here!
Update 12/10/2008: Apparently, there's a way to edit the VPC config file (.VMC) to disable time synchronization with the host operating system. Might make demos relying on a sprint/iteration interesting but it's very helpful.
We rely on the TFS / VSTS 2008 VirtualPC instances Microsoft pumps out for demos, presentations, and even some training. Yes, I can kit out a VPC on my own but it takes at least a day or two, it lacks the scenarios and test users, and sharing 20+GB files across the team can be challenging.
I'm excited to announce the TFS team will be refreshing the 12/31 expiring VPC instances soon...with SQL 2008 and all the latest bits! Thanks, Jeff Beehler for this insight.
